COMBINATION ENVELOP-OPENER, FOLDER, AND RULE.

srnorrrcArron forming part of Letters Patent No. 742,373, dated October 27, 1903.

Application filed March 11,1908.

To all whom it ,may concern.-

Be it known that I, DANA K. ALDEN, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in a Combination Envelop- Opener, Folder, and Rule, of which the following is a specification.

This invention relates to anew and useful combination envelop-opener, folder, and rule by the use of which envelops may readily be opened, papers may be folded and creased, measures taken or transferred to drawings, &c., and the device is also very useful as a paper-cutter for cutting leaves of books, as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, wherein- Figure 1 is a side elevation of the invention. Fig. 2 is an edge view of Fig. 1, and Fig. 3 is a cross-section on the line 3 3 shown in Fig. 1.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

The device comprises a blade A, which may be made of bone, ivory, metal, celluloid, or other suitable material. The ends B B are preferably made semicircular or suitably curved, as shown in Fig. 1. The edges and ends of said blade are beveled or rounded off Serial No. 147,312. (No model.)

' to an edge 0, adapted for folding or cutting paper, as may be desired. The side of the blade A is provided with a scale or rule D, divided in inches and fractions thereof, as shown in Fig. 1. If so desired, both sides of the blade may be provided with such scale or rule; but in practice it is only necessary to make such scale or rule on one side of the blade.

This device is a very handy and useful article for home and otlice use, comprising in a single piece a paper cutter or folder, an envelop -opener, and a rule for measuring or drawing purposes.

What I wish to secure by Letters Patent and claim is The herein-described combined envelop opener folder and ruler, consisting of a blade A, having beveled and sharpened parallel cutting edges 0, O, coinciding with corresponding curved and sharpened endsB, B,and having a rule or scale D, divided in inches or fractions thereof, substantially as and for the purpose set forth.

In testimony whereof I have affixed my signature in presence of two witnesses.

DANA K. ALDEN.
